The Ultimate Guide to iPhone Codes: Unlocking Hidden Features and Functions:
iPhones are known for their user-friendly interface and sleek design, but behind the scenes, there are hidden features that most users are unaware of. These secret features can be unlocked using special iPhone codes. Whether you’re looking to check your phone’s hardware, improve network performance, or activate hidden features, iPhone codes can give you more control over your device. In this guide, we’ll explore some of the most useful iPhone codes, how they work, and why they can be a game-changer for iPhone users.
What Are iPhone Codes?
iPhone codes are short numerical sequences, also known as USSD (Unstructured Supplementary Service Data) codes or MMI (Man-Machine Interface) codes, that allow users to access hidden features, settings, and diagnostic functions on their device. By simply dialing these codes on your iPhone’s dial pad, you can unlock functionalities that are often buried deep within the system settings.
Why Should You Know iPhone Codes?
You may wonder why knowing these codes is important. iPhone codes can provide you with critical information about your device’s performance, network settings, and security features. For instance, some codes allow you to check your IMEI (International Mobile Equipment Identity) number, which is essential for unlocking or troubleshooting your phone. Others can activate call forwarding, barring, or reveal the actual strength of your phone’s signal — something far more accurate than those bar icons at the top of your screen.
How Do iPhone Codes Work?
iPhone codes typically operate using the USSD system, which is the same protocol used by carriers to communicate with your phone. These codes are entered through the phone’s dial pad, and they often start with asterisks (*) and hash (#) symbols. When you dial a code, it sends a query to either your carrier or the iPhone’s internal system to activate or retrieve specific functions.
The Difference Between USSD Codes and iPhone Shortcuts
USSD codes are different from the shortcuts available in your iPhone settings or control center. While shortcuts allow you to quickly access certain features, USSD codes dive deeper into the technical aspects of your iPhone, enabling more complex functionalities like network settings, diagnostics, or security measures.
The Most Useful iPhone Codes
iPhone Code to Check IMEI Number
The IMEI number is a unique identifier for your iPhone, and it’s often needed when unlocking a device or reporting it lost or stolen. To find your iPhone’s IMEI number, dial:
- Code:
*#06#
Your IMEI number will instantly appear on the screen. It’s a good idea to note this number down somewhere safe.
iPhone Code to Check Signal Strength
The standard signal bars can be misleading, but you can use a code to check your actual signal strength in decibels. For a more accurate reading:
- Code:
*3001#12345#*
This code opens Field Test Mode, where you’ll see your signal strength measured in dBm. Typically, a number closer to zero indicates a stronger signal (e.g., -60 is better than -90).
iPhone Code for Call Forwarding and Waiting
If you want to activate call forwarding on your iPhone without diving into the settings, you can use these codes:
- Activate Call Forwarding:
*21*[phone number]# - Check Call Forwarding Status:
*#21# - Deactivate Call Forwarding:
##21#
This is particularly useful if you switch between different numbers often or want to direct calls to a secondary number temporarily.
iPhone Network Codes
How to Access Call Forwarding Settings
Instead of navigating through the menus, you can use:
- Code:
*#67#
This code will display the current call forwarding settings for when your phone is busy. You can also adjust settings for call waiting or forwarding when unreachable.
iPhone Code for Call Barring
To prevent incoming or outgoing calls, you can use the call barring feature with a USSD code:
- Code:
*33*PIN#(To activate) - Code:
#33*PIN#(To deactivate)
Replace “PIN” with the SIM PIN of your device. This is great for blocking unwanted calls.
Privacy and Security Codes for iPhone
Protecting Your iPhone with USSD Codes
Some iPhone codes can enhance your device’s security by preventing unauthorized call forwarding, tracking calls, or barring services. For instance, to prevent any form of call forwarding (like hacking attempts), use:
- Code:
##002#
This will disable all forwarding options on your device.
Secret Diagnostic Codes for iPhone
Diagnostic Codes to Test iPhone Hardware
Is your iPhone’s hardware working properly? You can perform diagnostic tests using these codes. For example, to access diagnostic tools and check your iPhone’s network, use:
- Code:
*#12345#*
Testing Microphone and Speaker
Test your microphone and speaker functionality by dialing these diagnostic codes to confirm if your iPhone is functioning properly. Though specific to iOS versions, third-party apps are often better for hardware tests.
iPhone Carrier-Specific Codes
Verizon iPhone Codes
For Verizon iPhone users, the following codes can be helpful:
- Check account balance:
#BAL (#225) - Payment info:
#PMT (#768)
AT&T iPhone Codes
